Thanks for writing in.
It can be papular urticaria
,insect bite reaction, secondary bacterial infection etc.
For correct diagnosis the images of the lesions and more info like duration,presence or absence of other lesions would be needed.
You can apply calamine
lotion over the affected area and also once a day hydrocortisone cream
application may be helpful.Also you can take Tab zyrtec
With images of the affected area and details of the symptoms a proper diagnosis can be made.
Images can be uploaded by the premium questions area.
I encourage you to visit a qualified dermatologist
for proper diagnosis and treatment.
Hope this helps.
